I have a few iPhone users whose inbox keeps reloading.  They can see their mail, then it disappears and starts loading the mail again. this started when we upgraded to MS Exchange 2010.

    Reload the IOS again and reconfigure the profile again. Check if that works, it is know issue

    I have Exchange 2003 and lots of iPhones and iPads. This issue happens a lot. Logs are huge because certain devices are syncing constantly. I had an open case with MS, they didn't care enough to really dig. It happens some with other devices, but a lot more with iDevices.
    Yes, breaking the partnership by recreating profile, or clearing on the server side will fix it for the short term. But could come back.
    I was just looking at this yesterday because my IIS logs were blowing up again. ~1GB per server, per day on the backend. About 500MB on the OWA/Activesync server.

    Same issue here and it happens with the latest ios 6.1.2... And on multiple accounts loaded on the same iphone from the same exchange server running exchange 2010 SP1... Really a pain...

    Are you by any chance using Onavo compression on those phones? I just removed the onavo profile and went to settings/reset/reset network settings and it seems to have fixed the issue (for now at least)

    Hi all,

    For us, I initially suspected something on the server end, and spent much effort bringing our Exchange Environment up to current service pack levels, tweaking all sorts of settings and even swapping out our firewall for something that could better control the timeout values.

    But in the end, removing Onavo solved the issue for us.  (For a couple we needed to completely reset the iphone back to factory default and start afresh - without Onavo).

    Since we have done this, I've had zero complaints.

    9+ months of frustration finally solved!

    I performed a Settings - General - Reset All Settings

    It cleared the problem on both of my problematic devices.
